UBT1H470MPD

The UBT1H470MPD is a radial-lead aluminum electrolytic capacitor offering 47 µF capacitance at a 50 V rating in a compact φ8 × 11.5 mm can. It is engineered for high-temperature environments and heavy-duty service where sustained performance at elevated temperatures is required.

Designed for automotive electronics and other demanding applications, this AEC-Q200 rated device provides defined ripple-current capability and long-duration endurance at +125°C, combined with RoHS compliance and standard bulk/bag packaging options.

Key Features

• Capacitance and Tolerance — 47 µF nominal with ±20% tolerance at 120 Hz, 20°C, suitable for power filtering and decoupling tasks.
• Voltage Rating — 50 V DC rated voltage for mid-voltage power applications.
• High‑Temperature Endurance — Rated for operation from –40°C to +125°C with an endurance life of 2000 hours at 125°C under rated conditions.
• Ripple Current Performance — Low-frequency ripple current 294.8 mA (120 Hz) and high-frequency ripple current 440 mA (100 kHz) to support AC ripple handling across frequencies.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) 0.10 at 20°C/120 Hz and leakage current specified at 70.5 µA, enabling predictable performance in filter and bulk-storage roles.
• Package and Mounting — Radial lead can (φ8 × 11.5 mm) with 3.5 mm lead spacing (±0.5 mm), offering a small footprint for through‑hole assemblies.
• Automotive Qualification and Compliance — AEC‑Q200 rated and RoHS compliant for designs requiring recognized automotive-level component qualification and environmental compliance.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to support prototype and production handling.

Typical Applications

• Automotive electronics — Power supply smoothing and decoupling in modules that require operation at elevated temperatures and AEC‑Q200 qualification.
• High-temperature power circuits — Bulk energy storage and ripple mitigation where continuous operation up to +125°C is required.
• Through-hole PCB assemblies — Compact radial can and 3.5 mm lead spacing fit constrained through‑hole layouts for control and power boards.

Unique Advantages

• Established high‑temperature capability — Specified endurance of 2000 hours at +125°C provides a measurable reliability metric for thermally demanding applications.
• Automotive-grade qualification — AEC‑Q200 rating supports use in automotive electronic designs that demand qualified components.
• Frequency-aware ripple handling — Separate low- and high-frequency ripple current ratings (294.8 mA at 120 Hz, 440 mA at 100 kHz) let designers assess performance across operating conditions.
• Predictable electrical behavior — Low tan δ (0.10 at 20°C/120 Hz) and specified leakage current (70.5 µA) enable accurate power‑supply and filter design calculations.
• Compact radial package — φ8 × 11.5 mm can with 3.5 mm lead spacing minimizes PCB area while retaining through‑hole robustness.
• RoHS compliant and packaging choices — Environmental compliance and bulk/bag packing options simplify procurement and assembly workflows.
